SHUTTER BOWER AND FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 564,548, dated July 21, 1896.

Application filed October 17, 1895. Serial No. 565,98 (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES ZIMMERMAN, a citizen of the United States,and a resident of Frederick, in the countyof Frederick and State ofMaryland, have invented certain new and useful Improvements in ShutterBowers and Fasteners and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters ofreference marked thereon, which form a part of this specification.

Figure lot the drawings is a representa tion of a perspective Viewshowing the invention in application. Fig. 2 is a perspective view ofbracket D, with bowing-rodin dotted lines. Fig. 3 is a sectional viewshowing double-locked positions of parts. Fig. 4 is a section on line:20 as, Fig. 3. Fig. 5 is a side view of shutter pull and catch. Fig. 6is a perspective view of sill-plate. Fig. '7 is a front view of bracketD. Fig. 8 is a perspective view of single socket.

This invention is more particularly de signed to be an improvement uponthe shutter bowers and fasteners shown and described in the patent toZimmerman and Zimmerman, No. 420,180, dated January 28, 1890, in thepatent to Vallin g, No. 445,210, dated January 27, 1891, and in my ownpatent, No. 537,334, dated April 9, 1895, and especially in the last twoof these patents in which double locks are employed.

The object of the present invention is mainly to provide a shutter bowerand fastener of this character having an improved double automatic lock,wherein both the locks are made by the engagement of the looking partswith one and the same cavity or socket of the sill-plate, and whereinthe parts are so arranged that the pivotal catch which engages saidcavity or socket to constitute one of the locks is adapted also to catchthe bowing-rod and throw its hooked end into engagement with itself andwith the said cavity or socket to form the second look.

WVith this object in view the invention consists in the novelconstruction and combination of parts, all as hereinafter described, and

pointed out in the appended claims.

Referring to the accompanying drawings, the letter A designates the sillof a windowcasi'ng, and B the shutter, which is'hinged to the side postof such casing in the usual manner.

0 designates the bowing-rod, having the hooked end 0. D is the bracketon the shutter to which the said rod is pivoted. E is the sill-plate,which has a series of sockets therein to receive the hooked end of thesaid rod in holding the shutter bowed to a greater or less eXtent,andwhich is also formed with the cavity or socket E, with which the rod andcatch engage to form the double lock.

F is a single socket affiXed to sill and which is engaged by thebowing-rod to hold the shutter in wide-open position.

G G is the combined shutter pull and catch.

The bracket D is formed with the upper and lower inwardly-projectingflanges d d, between the inner end portions of which the rod 0 ispivoted. The space between the said flanges gradually decreases towardthe base portion of bracket, and such space is also somewhat wider atthe front than at the back, both of which features are caused by theinclination of the upper face of the lower of said flanges and of thelower face of the upper flange. The purpose of this double inclinationis to cause the hooked end portion of the rod 0 to be elevated as itswings inwardly, so that it will rise above the sill as the shuttercloses.

The sill-plate E consists of a narrow plate, which is enlarged somewhatat that end wherein is formed the cavityor socket. The under side ofsaid plate is cut away, as indicated at E E whereby the sockets e E areopen at the bottom to permit the escape of water, dirt, and the like.The screws e,which secure the bracket in place, are seated in theextreme end sockets e, which are seldom used for the engagementtherewith of the bowingrod. This leaves the two intermediate sockets eand the cavity or socket E entirely unobstructed. The approach to thesaid socket or cavity is inclined, as indicated at E.

The combined shutter pull and catch consists of the pull portion G,having the screwseats g, the pull projection g, the vertical slot g andthe bearin gs g for the pivot-head g of the catch G, which is arrangedto play freely in the said slot 9 The catch G is form ed with an opening9 therethrough,at the inner edge of which is a downward-bent projection9 which is concaved somewhat on its inner face. This projection isdesigned to engage with the under beveled wall of the socket or cavity Eto form one of the locks. At the outer end of the catch G is an upwardlybeveled projection 9 The operation is as follows: In closing theshutter the hooked end of the bowing'rod, being elevated above the sill,comes into contact with the upwardly-inclined approach E of the socketor cavity E. At this time the beveled projection g of the catch G comesunderneath the hooked end of the bowingrod, and raises the same as saidcatch rides up the incline until it drops through the opening 9 thereofand into engagement with the socket or cavity E, the projection g at thesame time droppinginto engagement with the said socket or cavity. Theprojection 9 also forms a thumb-seat by which the said catch and therebythe rod may be raised out of engagement with the socket or cavity E, thesimple action disengaging both locks. This automatic act-ion is of greatimportance when the shutter is closed from the outside or from theinside by taking hold of the pull only with the rod hanging loose, orwhen, as is often case, the shutter is opened carelessly withoutengaging the rod with one of the sockets, and said shutter is blown toby the wind. It is in this feature that the present invention has animportant advantage over the fastening shown in the said Patents Nos.420,180 and 445,210, where the lock is not automatic. The presentinvention is also an improvement over the fastenings of the Patents Nos.445,210 and 537,334 in the construction of the double lock, and in thefact that both locks are made by engaging a common hole or re cess inthe sill-plate, whereby the release of one effects the release of theother, and whereby one look is a guard for the other. Other advantagesare found in the construction of the sill-plate and the bracket D.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, "is- 1. In a shutter bower and fastener of theclass described, the combination of the bowing-rod having the hookedend, the sill-plate having the socket or cavity E designed to be engagedby said end, and led up to by an inclined approach, and the pivotedcatch having an opening therethrough for said hooked end, a projectiondesigned to engage said socket or cavity, and a projection designed toengage said hooked end, substantially as specified.

2. In a shutter bower and fastener, of the character described, thecombination with the shutter-bracket having an inclined or cam face, thebowing-rod pivoted to said bracket and having a hooked end, a sill-plateformed with sockets c and with a socket or cavity E, led up to by aninclined approach, a shutterpull, and a catch pivoted to said pull, saidcatch having a projection designed to engage the said hook end, anopening therein through which said end engages the said socket orcavity, and a projection which is also designed to engage said socket orcavity, substantially as specified.

3. In a shutter bower and fastener, the combination with a hookedbowing-rod, and with a sillplate having sockets of the slottedshutter-pull G, and the catch G pivoted at one end within the slot ofsaid shutter-pull, said catch having the bent, downward projection gadapted to engage one of said sockets, the upwardly-beveled projectionat its forward end designed to engage the hook of said bowing-rod, andthe opening through which said hook is designed to drop into engagementwith the said socket, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

CHARLES ZIMMERMAN.
